PLANE Application led February 9, 1931. Serial No. 514,545.

This invention relates to an improved carpenters plane, in which the main object is that the handle and the cutter mounting is detachable in a single unit and can be immediately inserted into various plane shoes of di'lferent lengths. In other words, the various sized shoes have a fix-ed adapter into which the assembled handle and cutter will slide and thus forming a convenient method of changing from one sized plane to another and also eliminating the necessity of individual cutters on each plane.

To this and other ends which hereinafter appear, the invention consists in the novel features of improvements and combination 39 lustrating the fixed adapter with the cutting apparatus removed;

Fig. 5 is a plan View of a standard cutting tool mount;

Fig. 6 is a side view of the detachable sliding handle and cutting unit;

Fig. 7 is a bottom plan view of the sliding handle and cutting unit; and

Fig. 8 is an illustration of an assembled plane.

Like numerals or letters of reference indicate corresponding parts in the several views.

Referring to the accompanying drawings, numeral 1 is the blad-e clamp which holds blade 2 in a set position. The aligning lever 8 adjusts the blade from left to right, and the lifting claw 4, operated by the knurled knob 5, on the threaded spindle 26, adjusts `the blade up or down, the entire cutting means is held together by set screw 6. This is a well-known construction of cutting means usually employed in carpenters planes.

The handle 7 is held in place by bolt 8, which screws into stud 9. Screw 10 also serves to fasten the handle to the sliding bed of the cutting assembly.

Recess 11, is designed to accommodate locking screw 18, which astens the sliding cutting assembly firmly to the iXed adapter 17. Set screw 12, fastens the front end of the cutting assembly to its sliding bed. The numerals 13 to 16 inclusive, are small screws used as additional fasteners of the cutter to the sliding bed.

The tongues 17 a on the iiXed adapter are designated to receive the grooves 1719 on the sliding cutting assembly, thus interlocking the two sections of the plane.

The knob 19 serves as the front handle of the plane shoe 25 and is inserted over pin bolt 20, and held in place by screw 21.

Bumper screw 22, butted against heel 23, regulates an adjustment between the sliding cutting assembly and the plane shoe 25. The heel 23 is afiXed to the sliding bed by set screw 24.

rlhe said set screw 18 incorporated with the fixed adapter and sliding cutting assembly is the basis of my invention. With the iixed adapter as part of each of the various sized plane shoes, the cutting unit can be vadapted to the selected shoe, thus dispensing with the individual cutting units.

Having now described my invention, what I claim, and desire to secure by Letters Patent is-- A carpenters plane comprising a plane shoe having a tongued adapter mounted thereon in rear of the throat opening, a clamping screw threaded into said adapter, a detachable plane stock, a groove in the base of said stock for slidingly receiving said adapter, a slot in said stock for receiving the shank of said screw whereby said stock may be clamped interchangeably in adjusted position along one or another of said plane shoes.
